4 divides into 29 7 times, leaving a remainder of 1. Write 7 over the 8 and bring down the remainder (1), and also bring down the next integer (8). Divide 4 into 18; the result is 4 with a remainder of 2.
So now the quotient is 74 with a remainder of 2.
You could also write this as 74 2/4, or 74 1/2.
